Arrhythmias are detected by electrocardiography and treated by electric shock (often with an implanted pacemaker) or by drugs such as quinidine and digitalis.

用心电描记法可侦测到心律失常现象，可使用电休克或服用奎尼丁或洋地黄等药物来治疗。

A large number of hospitals in the region to fill gaps in the history of technology, such as in 1958 to carry out the chest tumor; in 1959 discovered the first case of leptospirosis in the region; in 1960 discovered the first case of scrub typhus in the region; in 1961 to carry out two rheumatic heart disease Closed mitral dilation and liver resection; in 1963 to carry out low-temperature under anesthesia for congenital pulmonary valve stenosis open heart surgery; in 1969 to carry out the tumor radiation therapy; implemented in 1975 brain tumor resection; in 1981 to carry out the second tip Valve replacement; in 1982 to carry out artificial joint replacement; in 1983 for the installation of a patient implantable artificial heart pacemaker .......

医院有着大量填补本地区技术空白的历史记录，如1958年开展胸腔肿瘤切除术；1959年发现本地区首例钩端螺旋体病；1960年发现本地区首例恙虫病；1961年开展风湿性心脏病二尖瓣闭式扩张术和肝叶切除术；1963年开展低温麻醉下先天性肺动脉瓣狭窄心脏切开直视手术；1969年开展肿瘤放射治疗；1975年施行脑瘤切除术；1981年开展二尖瓣置换术；1982年开展人工关节置换术；1983年为病人安装埋藏式人工心脏起搏器……。

By superfusion of ET-1, the hypoxiainduced decrease in RPF was remarkably potentiated (from 136±9 to 48±27 bpm) and the occurrence of pacemaker arrest was shifted to 20±6 min.

在缺氧的条件下持续灌流ET-1（1 nmol／L）20 min时，可显著加重缺氧所致的RPF降低，使起搏细胞的RPF由对照的136±9 bpm降至48±27 bpm（p.01），起搏细胞的停跳时间前移至20±6 min。

By superfusion of ET-1,the hypoxia-induced decrease in RPF was remarkably potentiated and the occurrence of pacemaker arrest was shifted to an earlier time. The h3,poxia-induced effects could be effectively attenuated after pretreatment with BQ-123,implying the role of endogenous ET-1 release in hypoxia-induced effects.

ET-1可显著加重缺氧所致的RPF降低，使起搏细胞停跳时间前移；而以ET*受体阻断剂BQ-123预处理窦房结标本后，则能有效地缓解缺氧对起搏细胞的效应，提示内源性ET-1的释放在缺氧效应中的作用。
